PROGRAMMABLE ALARM 5
The CEM7 control unit's programmable alarm 5 is activated associating the
operating mode of the programmable alarms (Settings table, parameter 23) to
one of the general purpose digital inputs (ENT1, ENT2, ENT3, ENT4 or ENT5) or
one of the engine alarm inputs (ATA, BPA or NA) in the CEM7J option. The status
of this input must be validated during a time interval (Times table, parameter 19,
20, 22, 23 or 24) for stabilisation (debounce) before generating programmable
alarm 5.
Detection of the programmable alarm 5 is set by default (Alarms table,
parameter 85) to never be activated: Programmable alarm 5 can be associated
with a time (Alarms table, parameter 86) to delay the moment at which the alarm
begins to confirm the alarm conditions. Programmable alarm 5 is set by default
(Alarms table, parameter 87) to perform no action (warning). Programmable
alarm 5 can be associated with a programmable text that appears on the display
of the display module when the active alarm is detected.
GENSET CONTACTOR SWITCHING FAILURE (CEM7 VER455 /PHG7 VER407
OR HIGHER)
The CE control unit's genset contactor failure alarm is generated if:
•
the genset contactor is activated through the CG relay of the
measurements module and the activation is not detected through
the programmed input (ENT1, ENT2, ENT3, ENT4 or ENT5) associated
to the confirmation mode of the genset contactor (Settings table,
parameter 6).
•
the genset contactor is deactivated through the CG relay of the
measurements module and the activation is detected through the
programmed input (ENT1, ENT2, ENT3, ENT4 or ENT5) associated
to the confirmation mode of the genset contactor (Settings table,
parameter 6).
It is possible to program a delay before checking the genset contactor failure
alarm (Times table, parameter 13) to allow time for proper activation of the
contactor. The status of this programmable input associated to the confirmation
mode of the genset contactor must be validated during a time interval (Times
table, parameter 19, 20, 22, 23 or 24) for stabilisation before being managed. To
enable the genset contactor failure alarm a set programmable input must be
assigned (ENT1, ENT2, ENT3, ENT4 or ENT5) which is associated to the
confirmation mode of the genset contactor (Settings table, parameter 6).
PROGRAMMABLE ALARM 3
The CEM7 control unit's programmable alarm 3 is activated associating the
operating mode of the programmable alarms (Settings table, parameter 15) to
one of the general purpose digital inputs (ENT1, ENT2, ENT3, ENT4 or ENT5) or
one of the engine alarm inputs (ATA, BPA or NA) in the CEM7J option. The status
of this input must be validated during a time interval (Times table, parameter 19,
20, 22, 23 or 24) for stabilisation (debounce) before generating programmable
alarm 3.
Detection of the programmable alarm 3 is set by default (Alarms table,
parameter 85) to never be activated: Programmable alarm 3 can be associated
with a time (Alarms table, parameter 86) to delay the moment at which the alarm
begins to confirm the alarm conditions.
Programmable alarm 3 is set by default (Alarms table, parameter 87) to perform
no action (warning). Programmable alarm 3 can be associated with a
programmable text that appears on the display of the display module when the
active alarm is detected.
PROGRAMMABLE ALARM 4
The CEM7 control unit's programmable alarm 4 is activated associating the
operating mode of the programmable alarms (Settings table, parameter 22) to
one of the general purpose digital inputs (ENT1, ENT2, ENT3, ENT4 or ENT5) or
one of the engine alarm inputs (ATA, BPA or NA) in the CEM7J option. The status
of this input must be validated during a time interval (Times table, parameter 19,
20, 22, 23 or 24) for stabilisation (debounce) before generating programmable
alarm 4.
Detection of the programmable alarm 4 is set by default (Alarms table,
parameter 82) to never be activated:
Programmable alarm 4 can be associated with a time (Alarms table,
parameter 83) to delay the moment at which the alarm begins to confirm the
alarm conditions. Programmable alarm 4 is set by default (Alarms table,
parameter 84) to perform no action (warning).
Programmable alarm 4 can be associated with a programmable text that appears
on the display of the display module when the active alarm is detected.
